Microstructure evolution in eutectoid steel during warm deformation in the temperature range from 600 to 700℃ was investigated by simulating hot compression test, SEM and thermomagnetic measurement. The effects of deformation and subsequent annealing on the spheroidizing of pearlite, refining of microstructure and dissolution of cementite were studied.

利用热模拟压缩变形、SEM和热磁法实验，研究了共析钢在600~700℃变形过程的组织演变规律，探讨了变形及随后保温过程对珠光体球化、组织超细化和渗碳体溶解、再析出的影响。

In order to compare the tribological properties of two aluminum matrix composites reinforced by different content of B4C particles ,the pin samples were prepared with them and friction and wear tests of pin-on-steel disc were carried out on a multifunctional tribometer.

The result showed that toughness of coarse-grain zone in X70 grade steel pipe HAZ was weak.Coarse grain,granular bainite,high binate and other unbalance low temperature variation result in quantity increasing. In addition to,impact toughness of coarse grain zone decrease with the t8/5 increasing.

结果表明：粗晶区是X70级管线钢热影响区中韧性较差的区域，粗晶区韧性恶化主要是晶粒粗化以及粒状贝氏体、上贝氏体等非平衡低温转变产物数量增多造成的，且粗晶区的冲击韧性随着 t8/5 的增加而降低。

It Was found that a complex ordered carbonitride is formed on hot-rolling and continuous cooling by the precipitation of Nb and V together with C and N in which the contents of Nb and V are changeable.

利用透射扫描电镜和能谱仪对Nb-V微合金化钢中Nb和V析出相进行了研究，发现Nb和V在高温形变和连续冷却中，与C，N形成一种复杂的有序碳氮化物，其中Nb与V的含量是可变的，其浓度比值C_(Nb/C_V随着析出颗粒尺寸的减小而递减，化学式可写成C_(1-x，N_(1-y)。
